Techopedia Explains Check Disk (chkdsk)
For the Check Disk tool to be used, the autochk.exe file needs to bepresent in the computer system. In most operating systems, admins have theoptions for what switches to execute with the Check Disk command. The mainfunctionality of Check Disk is to ensure the system or administrativeinformation regarding files, folders and similar data stored in a physical disk iscorrect. Most operating systems are designed to ensure this information iscorrect from start to shutdown of the computer. However, improper shutdown of the machine,removal of USB devices without safely removing them as well as malware or hardware errorscould cause this information to be corrupted. In such cases, Check Disk stepsin to sort out the errors and fix them. It performs an analysis and repairserrors on disks which are not in use. Fordisks which are in use, such as the C: drive in most Windows operating systems,Check Disk provides a prompt asking for permission to schedule the procedure for thenext time the system is restarted. If the answer is Yes, the Check Disk isperformed at the start of the next system run.
One of the many methods by whichCheck Disk locates errors is by making use of a volume bitmap with the disksectors allocated to files. However, Check Disk is incapable of repairingcorrupted data which appear to be structurally intact. If the /r command is used with Check Disk, it looks for and recovers any readable data in the disk’s bad sectors. If the /f command isused with Check Disk, it fixes any errors it finds.
